They shouldn't be looking there in the first place, says one employment consultant.

While social media seems like a brilliant way to learn about a potential new hire, employers should be discouraged from looking at a job candidate's Facebook page, said Mary Massad, president of the recruiting services division at Houston-based Insperity.

"When you see things an individual is doing online, it’s hard to ignore,” Massad told the Houston Business Journal. “You really don’t know a person’s character until you get to know them personally.”
